5 Claims.

closure member of any desired shape or form as,

for example, round, square, rectangular or the like, which is rugged and sturdy in construction and yet presents a pleasing appearance to the eye.

Another object is that of producing a closure member which is provided with abutments or grip-retaining irregularities on its outer surface so that it lends itself to quick removal by a person wishing to have access tothe contents of A further object is that of producing a closure member capable of assembly by automatic machinery and with the use of relatively unskilled labor so that the same may be produced in large .l quantities and at a nominal figure.

Other objects of the invention will, in part, be obvious and will, in part, appear hereinafter. The invention accordingly comprises an article of manufacture-possessing the features, properlties, and the relation of elements which will be exemplified in the article hereinafter described and the scope of the application of which will be indicated in the claims.

For a fuller understanding of the nature and `objects of the invention, reference is had to the following detailed disclosure taken in connection with the accompanying drawing, in which:

. Fig. 1 is a plan view of the reinforcing member of the closure;

Fig. 2 is an enlarged cross-section of one of the projecting lugs or abutments of the member shown in Fig. 1;

Fig. 3 is a side view of the drum of the closure before the reinforcing member is put in place.

Fig. 4 is a perspective view of the closure member with the reinforcing member in place, and

Figs. 5 and 6 are side views of the complete closure member with parts broken away to show the different steps in their construction, Fig. 6 .showing additionally one form of receptacle in association with the closure member.

Referring to the drawing, a reinforcing member or blank 1 is cut or stamped from a sheet of at material. This blank is provided with vprojections or abutments 2. Either during the stamping process or immediately thereafter each of the projections or abutments is scored adjacent the point where it is attached to the body of the blank as at 3. It is understood that certain departures from the general shape of the reinforcing member might be resorted to and that the scoring of the abutments might be dispensed with without impairing the practicability of the resultant product. j

A drum of the conventional type formed with a head 4 and a flange 5 is provided for association with the reinforcing member. These parts are secured together, as shown in Fig. 4, by gluing or in some other manner securing the drum head to the blank, it being noted that the scorings 3 preferably appear on the face of the reinforcing member which is so secured. Thereafter the projections or abutments are bent upwardly against the outer surface of the drum flange and are secured in this position by glue or any other suitable means. After the bending operation, the projections ordinarily assume a position of rest which is tangential with relation to the outer surface of the drum flange. This is best shown at 6 in Fig. 4. However, it is of course apparent that the projections could serve the purpose for which they are intended quite effectively even though they were made to conform to the curvature of the outer flange.

In order to complete the closure member and put it in condition for use, the drum head and attached body of the reinforcing member may be domed, as shown at 7 in Figs. 5 and 6. This dorning process, while not necessary, adds to the attractiveness of the completed member and tends to strengthen the same. If it is desired to give the closure member a more pleasing appearance, additional layers of colored paper or paper bearing printed indicia may be added, as shown at 8. In Fig. 6 a container 9 having a window 10 through which the contents of the container may be viewed is shown in connection with the closure member. It is, however, obvious that the closure member described might be associated with various forms of containers. v 'It is also apparent that the closure member above described could be produced, for instance, by substituting the body of the reinforcing member for the head of the drum member, thereby reducing the weight and bulk of the resultant product. Also various changes in the design of the reinforcing member or blank might be resorted to so long as the projections or abutments were kept integral with one another, and other changes might be effected without departing from the spirit of the invention herein set forth.

Having described my invention, what I claim as new and desire to secure by Letters Patent,

l. A closure member including a head, a flange associated therewith, a disc for association with said head, and laterally spaced gripping abutments carried by said disc at right-angles to the surface thereof and tangentially disposed adjacent the outer surface of said flange.

2. A closure member including a head, a ange associated therewith, and integral laterally spaced reinforcingv strips tangentially mounted on the outer surface of said flange.

3. A closure member comprising a flange; a head mounted on said ange, and laterally spaced gripping abutments carried by said head tangentially disposed adjacent the outer surface of said flange.

thereof and tangentially disposed adjacent the outer surface of said flange, said abutments being formed with a line of scoring adjacent their point of juncture with said disk.
